Abstract: With the occurrence of oligopoly among manufacturers and suppliers in the civil aviation market, we establish a two-level game theory model to study the problem of competition and decision making between manufacturers and suppliers. In the higher game, the aeroplane manufacturers aim to determine their output and purchase quantity for each engine supplier based on market profit. While in the lower game, engine suppliers determine production by solving an optimization problem. We use the conditions of the lower game to obtain the constraints for the higher game. Then we establish the algorithm for the problem. By simulation using the actual conditions of the market, we can justify the rationality of the model. Therefore, we discuss what impact the production of COMAC C919 will bring to the market as well as the decision making behavior of its pricing.
